PHILIP H. REED, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO GAS STOVECOMPANY, OF SAME PLACE.

WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 403,138, dated May 14,1889.

Application filed April 3, 1888. Serial No. 269,453. (No model.)

To all whom it may concern:

Be it known that I, PHILIP H. REED, a citizen of the Dominion of Canada,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water-Heaters, of whichthe following is a specification, reference being had therein to theaccompanying drawmgs.

This invention relates to new and useful improvements in Water-heaters,especially designed for use with gas or as a waterfront for gas-stoves;and the invention consists in the peculiar arrangement and combinationof the parts, all as more fully hereinafter set forth.

In the drawings which accompany this specification, Figure 1 is avertical central section of my-heater as arranged with a singlewater-ring. Fig. 2 is a cross-section thereof on line 00 5c in Fig. 3.Fig. 3 is a horizontal section on line y y in Fig. 1. Fig. 4: shows themanner of combining a series of waterrings. Fig. 5 is a diagram plan ofa larger combination of water-rings, and Fig. 6 is a cross-sectionthereof on line 2 z. i P A is an annular water-heater or water-ring,preferably of rectangular shape in cross-section and cast in oneintegral part, and provided with an annular gas chamber or ring, B,preferably cast integral with the waterring, on or near the outer edgeof the bottom thereof. The water-ring is provided with the inlet C andthe outlet D, suitably screwthreaded to receive connecting-pipes.

The gas-rin g is preferably circular in crosssection, and is providedwith the inlet a to connect with the gas-supply pipe E and with theperforations 1) upon the inner side at intervals around the ring. Thegas-supply pipe E is provided with the usual cock, F, and mixers F toadmit a sufficient amount of air to form with the gas perfect combustionwhen issuing from the burner.

This single water-ring type of heater is mainly designed to be used inconnection with ordinary water-tanks, G, for house-supply, as shown inFig. 1, wherein the inlet-pipe C is connected to the base of the tank bythe pipe H, and the outlet D is connected to the tank at a higher pointby the pipe I. A sheetand a convenient support upon which articles maybe heated.

In practice, the parts being constructed and arranged as described andshown, the device is intended to operate as follows: Gas being admittedto the burners and lighted, the flames impinge directly upon the underside of the water-ring, and, being directed toward the center, arecarried up through the opening K, in contact with the inner wall of thewaterring, into the heating-chamber formed below the cover; and, as theonly means of exit for the products of combustion is by passing outunderneath the cover, a draft is created which carries the flames andgases of combustion over the top and then down on the outside of thewater-ring, thus causing them to completely encircle the water-ring, asshown by the arrows in Fig. 1. The result is that the water in the ringis rapidly heated, and, rising through the pipe I into the upper part ofthe tank, is replaced by cold water from the lower part of the tank,thus forming a rapid circulation.

Fig. 4 shows the manner of constructing a water front or heater composedof two or more rings. This is preferably done by inverting the rings andconnecting them in vertical series by means of the tubes L. By invertingthe rings and burner each burner is brought into the same relation tothe ring above it as it has to its own ring when not inverted. An extraburner may be provided for the lowest ring, which would otherwise bewithout a burner. The whole pile is inclosed in a jacket, M, providedwith a row of holes, N, opposite each burner for the admission of air,whereby the products of combustion are carried off through the space inthe center of the rings. By inclosing the Whole pile of rings into adrum or stove of any suitable form or design and provided withair-apertures O, coincident with the apertures N, the

heat may be further utilized as a means for heating the room in whichthe device is located. Suit-able connect-ions, P and R, 0011- nect thelowest and highest rings of the waterfront with the boiler in the usualmanner.

The connections between the individual rings are made alternately uponopposite sides, so that the water in its circulation must necessarilypass around each ring before it passes into the ring above it to receivethe full benefit of the heat.

It is obvious that the rings may be combined in series in the samemanner as shown without inverting them, and it will furtherbe seen thata water-heater of any desired capacity can be constructed by increasingthe number of rings in combination, Fig. 5 showing a diagram plan, andFig. 6 a cross-section thereof, of such a larger combination of rings,all included into one circulating system.

I do not limit myself in the use of my in- "ention to heating water fordomestic or other use, but claim, also, the application in a circulatinghot-water system for heating purposes or for generating steam by meansof gas.

Aside from the simplicity and economy the obvious advantage gained inconstructing the water and gas rings in one piece is that no supports oronly a minimum of support need be provided. In the arrangement of thesingle heater, for instance, as shown in Figs. 1, 2, and 3, the heateris entirely supported by the circulating-pipes, together with theburner, without any extra support, and it may thus be arranged at anyconvenient place without sacrificing valuable floor-space. The cover orcase J extends over the top and down on the outside of the water-ring,and preferably, also, on the bottom, to exclude all contact with thecold air against any part of the water-ring, suitable exits orperforations, 0, being provided in the lower part for the escape of thegases of combustion.

That I claim as my invention is- 1. The combination, in a water-heateror water-front, of a water compartment or boiler provided integrallywith a gas compartment or burner, substantially as described.

2. The combination, in a water-heater or water-front, of the annularwater-ring and the annular gas-ring or burner cast integrally with it onthe under side thereof, substantially as described.

3. The combination, in a water-heater or Water-front, of the annularwater-ring A, substantially rectangular in cross-section, and theannular gas ring or burner B, cast integral with the Water-ring aroundthe outer, upper, or lower edges thereof, substantially as de scribed.

4. The combination, with the Water-ring and the gas-ring formed integraltherewith, near the lower outer edge thereof, of an opening in thecenter of said ring, and a jacket, J, around said burner and water-ring,substantially as shown and described, and for the purpose specified.

5. The combination, in a water-heater or waterfront, of a verticalseries of single Waterheaters, each consisting of a water-ring and a gasring or burner integrally formed therewith and of intermediateconnections between said water-rings alternately upon opposite sides,substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses,this 17th day of March, 1888.
